If it's not too much trouble, could you provide a link? I think I understand that it's all about randomness. If it's on your side, the Minotaur will defeat the Champion, but that's the case in any game. You need to consider the odds. The Minotaur needs to block the attack much more than 20 times in a row. The most I've seen him block is 3-4 attacks in a row.

It's all about save/load here. You catch the morale, luck, and even without them, you can defeat the Champion. Save before each attack, and that's it. Your Minotaur always deflects the Champion's attacks, and he attacks too. Eventually, after a certain number of attempts, he'll defeat him. Didn't manage to deflect? No problem, just load the save and try again. These things work in offline mode, but it's impossible in online mode. Although, in essence, it's cheating. However, it's difficult to catch... But if you want, it's possible. Daily save file checks.
